Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0016] The update optimization method of the farmland shelterbelt of the embodiment of the present invention is carried out according to the following steps:

[0017] Step 1, select a coniferous tree species with a lighter side, and the maximum growth height is equal to or greater than the existing poplar forest belt; the selected coniferous species is Pinus sylvestris, and select 2-3-year-old Pinus sylvestris container seedlings or tree height 1.5 For the large seedlings of Pinus sylvestris more than 1 m, the seedling height of the selected Pinus sylvestris container seedlings is more than 50 cm, and the ground diameter is more th...

Abstract

The invention discloses an agricultural protection forest updating and optimizing method which comprises the following steps: step 1, selecting less-hazard coniferous arbor species, wherein the greatest growth height of the less-hazard coniferous arbor species is equal to or greater than that of an existing aspen forest belt; step 2, performing forest planting on the existing aspen forest belt on one side of an original aspen forest protection forest belt in an out-belt updating mode by use of the less-hazard coniferous arbor species selected in the step 1; step 3, performing forest planting in summer and rainy season of each year; step 4, when the average tree height is more than 10m, performing clear cutting on the existing aspen forest belt, thereby finishing forest belt updating and transforming. According to the agricultural protection forest updating and optimizing method, the existing aspen forest belt is updated and transformed by virtue of the selected less-hazard coniferous arbor species, a mode of binding large seedlings and forming a forest once is adopted, so that the purposes of reducing land occupation and alleviating hazards are achieved; furthermore, the aspect change of the forest belt is not obvious, the protection efficiency is stable, sustained and stable protective benefits in a protective forest updating and optimizing process can be preserved.

Description

technical field [0001] The invention belongs to the field of shelterbelt construction, in particular to a method for updating and optimizing farmland shelterbelts. Background technique [0002] The increasingly serious natural disasters and the deterioration of the ecological environment are a huge threat to the current agricultural modernization. There are about 70,000 km in the Three Norths of my country alone. 2 In recent years, almost all parts of our country have been harmed by sand and dust. According to the data in the white paper "China's Environmental Protection (1996-2005)", the desertification area in my country has reached 1.7397 million km 2 , the average annual direct economic loss is 2 to 5 billion yuan, and the loss of grain is 5 to 1 billion kg. The rapid increase of the global population, the serious deterioration of the environment, and the shortage of food supply have become thorny problems facing the world today. Especially in developing countries, t...
